Boris Johnson mocks Keir Starmer during Kings Langley book launch
Boris Johnson took a cheeky swipe at Sir Keir Starmer and he told him to "get on your bike" at his dad's book launch in Dacorum.
The former Prime Minister made the jibe while celebrating a legendary motorbike trek with father Stanley and brother Max at the Old Palace in Kings Langley. Footage shows the trio squeezing onto a vintage BSA bike in retro helmets as they recreated a 1960s expedition.
Boris joked the Prime Minister might soon need a motor of his own, saying: "If Keir's looking for a way out, he could do worse than one of these."
The quip came as Stanley launched In the Footsteps of Marco Polo - his account of a globe-spanning journey first attempted in 1961.


Stanley and two pals set off from Oxford on 500cc BSA Shooting Star bikes, riding across Europe and Asia through Turkey, Iran and Afghanistan.
They made it to the remote Wakhan Corridor on the Afghanistan-China border - but were forced to turn back when they couldn't cross the High Pamirs.
More than six decades later, Stanley finally completed the epic route with son Max in 2023, crossing China from the Himalayas to Beijing. At the launch in Kings Langley, the Johnsons recreated an iconic 1961 snap - clambering onto a classic BSA motorbike in old-school goggles and helmets.
Boris hailed Britain's engineering heritage and paid tribute to the bikes that powered the original adventure. He said: "Dada has always had a taste for adventure, and it is wonderful to see him celebrating a journey that began on a British motorbike more than 60 years ago.


"I'm delighted to be here with him, Max and these magnificent old machines to mark a book that is every bit as spirited as the journey behind it - and to celebrate a great name in British motorcycling heritage.
"BSA stands for the quality, ingenuity and ambition that helped carry Stanley, and British engineering, around the world."
Stanley said: "It is a huge pleasure to launch the book here in Kings Langley with Boris and Max, and to pay tribute to BSA, which played such an important part in the original journey.
"Max and I had the great good fortune to finish the route together in 2023, and having Boris here today gives the launch a splendid family send-off."
Boris later pulled pints behind the bar at the venue.
